There is no concavity difference between the offsets actually, it's the sizing of the wheel (9.5" and 8.5") that is making the concavity different.
As for the ET22 not fitting right, the Z4M can very easily fit a ET22 in the back. Here's a Z4M Coupe with that set up in the rear, (yes, it's a 19" CSL wheel, but it's still 9.5" ET22, so the visual aspect of it will look identical):
